Have you considered getting a pet? They in no way replace human relationships but pet companions can be a lot of help for loneliness. Pets are generally more friendly and less judgmental than people too.

Perhaps you could go out with a group for singles if there is one in your area. I did that and I didn't find Mr Right but I did enjoy the conversation. The group in my area has dances once a month but I don't know how to dance so I just went out with the group to a restaurant to eat. Being with the group you don't have to worry about carrying the conversation and you get to meet a number of people in a short time.
